The Brazilian has undoubtedly been one of Chelsea’s shining lights this season – this his seventh goal in all competitions – but the support from Eden Hazard and Diego Costa has not always been there.

But here Costa did his job as target man expertly as he fought off the challenge of a Porto defender to lay the ball off for Hazard, who teed up Willian to do the rest with a perfectly-weighted pass.

All of Willian’s six previous goals this campaign have come from direct free-kicks, but this might be the most pleasing from Mourinho’s perspective as Chelsea aim to rediscover their form of last term.

The Blues go through as Group G winners and will therefore avoid favourites Barcelona, Real Madrid and Barcelona in the last 16 – important considering that winning the competition could be their only chance of playing in it next season because of their 14th-place position in the Premier League table.
